You guys rock and I'll be a customer for life. Gouging people who care about the sport, that's just shitty business practices. I hope people remember this down the road.

@John Beige Sounds good, thanks!
No myths - just data driven facts. Love it.
Glad the video was of value to you. Have a great day!
You guys freaking rock for actually putting data behind this, rather than opinions on gun forms. I've shot hundreds of 9mm loaded with small rifle (DA/SA CZ) primers, and I've had no pressure issues.
Thanks, glad it was beneficial!
True story. I've been shooting magnum primers in my small hand guns and my .45 acp. Couldn't find regular primers.
Been doing it for years, started by working up reduced loads with magnum and rifle primers just to be safe until I reached max loads and found out there were no pressure signs and virtually no difference
@@tn-s197 If you go to forums it's probably the number 1 question asked in primer shortages like this. So many chime in saying you will blow up your gun, it's not safe , you will blow your hand off. It's laughable on sites gun forums how many so called experts no nothing. Shoot safe and have fun.
Just to elaborate on what knowledge I have gathered small pistol magnums are almost exactly a reg small rifle as far as cup thickness and most all small primers do not differ on their charge it all has to do with what pressure they can withstand from the load....small pistol magnums for example are made thicker inside to withstand higher pressures from magnum loads....so while I have had no bad experience using heavier primers in lighter loads I try to not reverse the concept....example being I wouldn't use a standard small pistol primer in a small rifle cartridge that had a lot higher case pressure than most small pistols...if I had to I'd use a magnum pistol primer and be careful working up the load.....but as far as using magnums and rifles in pistol cartridges, basically as long as it will set it off you are good.....
This really destroys the old rumors I've always heard.
I inadvertently loaded a few hundred rounds with small rifle primers last year and when I realized my mistake I was concerned about firing them. I spoke to a few knowledgeable people and they said said it was ok and not to worry. No one could tell me why though. Now I understand.
I believe Rifle primers are 0.005" longer than Pistol primers... so you may need to seat them a little harder to be flush. At least this is what I found when measuring Large Pistol and Rifle primers. I did not measure the 'small' rifle/pistol primers.
@@n2omike Interesting. When I have both at the same time I'll mic them.
What about this one I’ve seen doing the rounds, just wondering what your thoughts are about these guys that are using cap gun powder & even the old normal strike anywhere match head scrapings to then “reuse” the ammo, case /primer & bullet. I must admit to flinching on his first shots and I wasted even there. I don’t want an argument about this, I just want to start a conversation on this issue, I personally would only use this as a extremely last resort kinda thing but I must admit that they seemed just as good as the normal stuff but would in no way want to have to rely on them. Especially if I had them a week or two. . Thanks 😊
This just made my day! Thank you for the simple, straightforward answers with the actual data! I've been trying to figure this out for months!
I'm happy that you've shown some actual pressure tester data, thanks much.
Thank you for tuning in
Im 65 been reloading since teenager i knew these facts but nice to see guys telling people reality and facts concerning pressure levels . Thanks for this public service you guys are great
Rebecca, you are female right?
@@roberttaylor6030 no this is rebeccas husband using her acvount sorry
@@GaryBlankenship96b40 LOL, I thought it might be something like that. I've just never known a woman who reloads. I'm sure there's a few out there somewhere though. Probably some competitive shooters do.
@@roberttaylor6030 My girlfriend has been reloading with me for 5 years. I have been reloading for 37 years. She has a good solid foundation for the reloading process, but she is monitored modesty for charge weights and neck tension. Other than that, of I say we need 308's, she loads the Peterson brass with 43.5 gr. of Varget, 168 gr. Cutting-Edge MTAC at magazine depth for the custom AR10 I built for her.
@@kenmarsh That's cool, most women, or people for that matter are glad to help you shoot up your reloads but aren't around when you need to reload more. That's my wife and son though neither one shoots all that often anymore.
Charging pre pandemic prices...
God bless you.

You win the UA-cam video of the year award. I've been staring at several thousand wolf small rifle primers in my reloading room for the last 6 months. I spoke with a customer service rep for one of the powder manufacturers and asked if I could substitute Magnum or rifle primers in my 9 mm loads. I thought he was going to jump through the phone. He said it wasn't safe.I've used small pistol Magnums in my 9-mill loads before without issue. I was reluctant to use the small rifle primers. I strongly recommend anyone doing this and using a Glock pistol install one of the wolf extra power firing pin springs. It is a 6 lb spring compared to the factory 5.5 lb. It does not increase trigger pull much at all. It provided 100% reliable ignition with my Magnum primers. I had about 10% fail to fire when I used the factory spring in a Gen 5 Glock 19. Thanks again for putting out a useful video with actual pressure test data. No one else has done this
Glad the video was beneficial, and thanks for the kind words!
just because they work at a place like that doesn't mean they know squat about it. Just like people who work at gun/outdoors stores, most don't know squat and just wanna make sales
Awesome information. No one I know personally , who reloads , has been able to answer my questions on primers the way you have in 10 minutes. Great content! Thank you!
This is probably the most useful knowledge I have ever gotten off of UA-cam. Many thanks!!!
That's great to hear! Thanks for watching!

The video that gave me all the answers without wasting ammo, primers and time to test and chrono loads with diff primers. I’ve been reloading for 10+ years but never bothered to look this up. Thank you!!!
How has it taken me TWO YEARS to find this video?!?! FANTASTIC information. Thank you Super Vel crew!
This is Awesome, I had no idea that this was the case. Thanks for the data!
No problem! Thanks for watching!
Good info. I’m loading 9mm with small pistol magnum primers and now you have given me the data that I needed. Thanks
Thanks for the heads up. I really appreciate the information on small rifle primers being used in small pistol cartridges.
Wow thank you! I have been reloading for 43 years and always wondered about this primer data. Thank you so much for doing the legwork and testing. Amazing results.
No problem, glad it was helpful!
Very cool info. I actually have a considerable amount of small rifle primers, but I no longer have a small rifle. So... this info was invaluable. THANKS!!!
Beautiful. You’ve answered an age old question for me and all of us, as a lifelong handloader.
Thank you! I’ll be sending you some business. I’m one of the lucky ones who stocked up deep and heavy. Tons of primers of all types.
This was great information, truly appreciate you taking the time for this testing!
Thank you very much.Relieves some of the concern that I had with my Dad’s leftover primers.
No problem! Glad the video helped out
Thank for showing everyone the pressure differences between the different primers
No problem!
Thanks for the info. It has eased my mind about using small rifle primers when they were all i could get
Likely the most useful video on youtube...cannot thank you enough!
Awesome demo. I was running low on small pistol, but got plenty of small rifle and you just made my day.
Happy to hear it!
Great ammo, Great service, no gouging, keeps us up to date on ammo, thank you for being an honest American company
Very well spoken. Appreciate you taking the time to make this video. Thanks again, Travis; 2A Tactical LLC Boise, ID
Excellent video. Thanks for taking the time to run the tests and present the facts.
Our pleasure! Glad it was beneficial for everyone!
Been doing this for years. But it never fails some safety Karan comes along and tells me I’m unsafe. So I leave it to myself. Thanks
You've been ahead of the game it appears!
Thanks for putting this out. Best video with data to back it and super helpful!!
This is the best video on being able to mix primers thanks for the info
Excellent video, a friend asked me about using small rifle primers for pistol loads. Now I can reassure him it is fine. Thank you so much!
Super Vel, thank you for this video! Lab tests for pressure are here are a first, and definitely helps with options during this primer shortage.
Thank you sir!!! Data over opinions anyway of the week.
This is fantastic information, thanks for sharing and for the actual data! I'm one of those detail guys from Missouri the Show Me state! :-) You're awesome and for the fantastic information I will try my best to support you with what ammo I purchase and will send my friends your way!

I can't thank you enough for this information. This what I've been searching for as a competition shooter who does his own reloading. Please keep up the good work.

Outstanding video!!! These are the types of videos that add to all of our knowledge. Truly appreciated. It would be very informative to have a similar video showing the same test with standard large pistol and large pistol magnum primers.
Thank you for the kind words and for watching! We have more videos in the works!
Great piece. I have been loading for over 50 years and I can tell you he is spot on. I had to load 9mm luger and low and behold I was out of CCI-500 so I substituted CCI-550, 124 gr Nosler, and Hodgen HS-7 (Speer data). No Problem.
I am glad I found your site. I reload and did not know that I could use the 3 different primers too reload my revolver rounds. I have all stock hammer springs and I will be able too reload a lot more rounds with the different primers without the worry of excessive pressures. Thank you for the great video.
That's great to hear!
don,t do that with the fast powders
One time I screwed up and bought large pistol magnum primers to use to reload .45 ACP. When I shot them, i noticed no difference in performance or accuracy. Your video confirms that there is really not much difference. It's a great video and confirms that it's safe to use the wrong primers and that you won't blow up your gun or injure yourself. Thanks for clearing up any of the myths that exist.
Glad the video was beneficial, thanks for watching!
Great video and tons of respect to you for putting it out there. Reasonable prices too. You've got yourself a new customer. When stuff is back in stock you'll be my go to. Thanks
Happy the video was of value to you, and glad to hear we have a new customer. We really appreciate all of the support!

Thank you. I’ve been looking for this kind of information. Why this doesn’t show up higher in search results baffles me. Just wish I’d been able to find this video sooner.
Thanks big time for the video we already knew small P and small R interchange, but weren't sure to try put small R primers in 9mm cases. AWESOME !!!
great work.. I think this pretty much concludes that primers don't have an impact on the case pressure, at least in pistol. As long as the primer properly burns all the powder in the case, the pressure or muzzle velocity should be consistent throughout different types of primers.
Excellent video, answers a lot of questions…thank you sir!!
Thank you Super Vel !!
This video is exactly what all reloaders have been wanting to know. I will definitely keep this in mind when buying ammo. I didn't even know people could send primers to Super Vel to have ammo loaded. That is spectacular! Thanks again for info that is actually backed up by real data!!!
No problem, thank you for watching!
I know I'm very late getting to watch this and comment, but I just wanted to tell you how much I appreciate good information. Not just your say so, but the on camera testing to confirm it. I'm a new reloader, and just about to finish my first box of Remington primers for 9mm. Its a milestonte, from nervous Nellie to tweaking, the quality of my ammo, and having someone( a competition shooter) teach me the safe habits of reloading and how to conduct load developement . Thanks again, its amazing I am always learning.
Awesome information. I have so many small rifle primers and really was not sure if I could load them in place of my small pistol so this helps a bunch
Thank you for the testing and results from the testing!
Fantastic presentation and data. Thank you for putting together such a great topic for us!
This was a great video. Very informative. Thank you
Awesome video! Thanks for making it! I get into this debate with my customers all the time. Mahalo from Hawaii!
Glad you liked it! Have a good one
Thank you very much for publishing this video. I load different calibers, both pistol and rifle, using their respective “appropriate” primers. Now, I know I can mix and match within certain safety parameters. Much respect, sir! I salute!
Our pleasure! Thanks for watching
Thanks for a useful video. I have always wondered what the difference would be. Good to see the Super Vel name still out there.
No problem, thanks for watching! And we're glad to be back!
Thank you for answering this question with real data, not opinion like so many others.
Thank you, I was considering using rifle primers in my 9mm. just like the 38 super guys. But I didn't know who to ask for advise. I will sub.
1 lab test is worth 1000 expert opinions!
This is the best video I've seen all day, thank you so much for sharing this. I have passed by small rifle primers several times thinking them unsuitable for 9mm. Oh well, I won't make that mistake again! On a side note, I learned that it is not wise to (mistakenly) use large pistol primers in place of large rifle primers. Remington packaging looks similar for both, D'Oh! I caught myself after 20 rounds, thankfully. I took a chance and fired them (7x57 Mauser loads, loaded below maximum in the Speer manual). Most were okay, but a couple had minor piercing. I was lucky as well as stupid. After rooting around on the internet I found others that had worse luck than I did with pierced primers on different calibers. The takeaway lesson is to carefully double check ALL of your components and charge weights before proceeding. A kinetic bullet puller is also a sound investment. Great video, thank you!
Thanks so much for this info. I bought a box of 1000 small pistol magnum when that's all that was left. Thanks for the peace of mind.
No problem!
You guys are awesome, one of the few companies that prioritize the customer. Customer for life right here!
Thank you for your kind words and support! It means a lot to us!
Thanks so much for this great informative video on an important safety factor of primer use and applications. Recently I used some old CCI Small Rifle Primers in 45 APC equipped with the SP primer pockets. Chronograph showed appx. 2-3.5 FPS faster speeds, but no pressure signs at all, using IMR 700X powder. I use a Frankford Arsenal hand held primer installation tool, equipped with adjustable primer depth setting. I set all of my primers @ .002"-.003" below the surface or past flush. When I measured the primers, both the SR and SP are exactly the same dimensions in depth and diameter, where the LR are different that the LP. Again; thanks to your video with specifications and excellent testing, I am comfortable to have checked my use of the SR primer in my 45s.
Thank you for your clear and concise work on this. As a new reloader it's helpful to see and now I am curious to try myself and run some loads through my chrono. Thanks for the inspiration to nerd out on more details haha
Excellent publication, timely and very helpful.
Glad you liked it!
Thank you for your testing. From experience, the S&W M&P and the SCCY 9mm pistols have a hard time firing the small rifle due to the light strikes. Most others seem to fire it well. .380's loaded with 50-60 year old CCI SPM's from a Ruger LCP also functioned well.
Good test! Thanks for sharing!
Brilliant! I have been wondering about this. Now I can start reloading 9mm again.
Thanks so much for cutting to the chase with true scientific data. The numbers don't lie. A chronograph is something most have access to but your Test Barrel and pressure data is the definitive analysis that we are all seeking. You rock! Just bought a Brick of Federal 200 Small Magnum Pistol Primers to feed my 9mm pistol, carbine, and .38 Special EDC. Yes, Sportsmans had five bricks under the counter today. I got lucky. 44 guys at the front door at the opening.
Awesome. Never had actual proof positive for the primers as shown- so never tried it... now can see its a doable thing. Thank you. By the way - Super Vel is is nice to see- again!
So happy for this info- wow you are well equipped having your own pressure reading device - supper cool. Keep up the good work
Great video and information! I have some Super Vel 44mags from the 60’s given me by my father👍
Thank you very much for your research! I have been dwelling on this and very interested! Thanks for sorting this out!!!!!!!!!!!!!!!!!!!!!!!
No problem!
This kind of video makes UA-cam worthwhile. Thank you!
Wow!!! What a great informative video, THIS IS a difference maker. Thank you for the video!
My shelf is loaded with all 3
You made me very happy
Thank you
No problem!
Great ammo, good prices, no gouging, let's keep a great American company going that is doing their best for us
As a new to reloading this is very helpful info thanks for shearing.
This is excellent info with real proof. Thank you
Thank’s for the information and test 👍🏻 That was helpful.
I love your Memphis Bell poster 🥰🤩
Awesome, informative video. I commend y'all for putting out this info because "most", if not all, ammo manufacturers would NOT be so willing to impart this kind of info considering liability, etc. Thanks.
Excellent Block of instruction!!! Much appreciated!
Thanks! Glad it was helpful!
Very timely information! Thank you!

Awesome vid. Thanks for posting!

Awesome video and info!!
This is fantastic info, thanks for putting this together, subscribed.
Excellent...I've been reloading since 1974...until now this has never been an issue.
Thanks for showing us reloaders this data...Until just recently...before I found 3K S P primers..I considered using S R...but hesitated..
Thank you, you truly answered questions the answers I have looking for. You clearly explained.
Most excellent video. And great that you're using PPE.
Just what I was looking for. Thanks!
Glad to hear the video was helpful!
Great video thank you so much I was thinking about this for a while and this is the best video out there on the subject
Thank you for credible accurate relative information! Well done!
Thanks Brother! I will try the small rifle primers in my 38 special loads.
I have been wanting to see a video about this. Great information
Glad it was helpful!
best video i have ever seen. i subbed. good shit my dude. for real
Thanks for the kind words and for the sub! Have a good one
Reloading manuals that I have read say don't mix. You are the first source that I have heard say it is ok. In a pinch I would do it.
Smiling!
Thank You! I just loaded a couple hundred 9mm with small rifle primers CCI 400 (out of CCI 500) tested them yesterday with 3 of my 9mm and they all did well with them. I checked the specs and the one thing I did run into was the primer is just a little longer and you have to press harder are you get a little wobble when you set them butt down on the desk, I needed the right arm work out anyway.
